Here is the full Text from the translation of chapter nine that I have found.
Quote: 4. Except for those among the polytheists with whom you had made a treaty, and did not violate any of its terms, nor aided anyone against you. So fulfill the treaty with them to the end of its term. God loves the righteous.
5. When the Sacred Months have passed, kill the polytheists wherever you find them. And capture them, and besiege them, and lie in wait for them at every ambush. But if they repent, and perform the prayers, and pay the alms, then let them go their way. God is Most Forgiving, Most Merciful.
6. And if anyone of the polytheists asks you for protection, give him protection so that he may hear the Word of God; then escort him to his place of safety. That is because they are a people who do not know.
7. How can there be a treaty with the polytheists on the part of God and His Messenger, except for those with whom you made a treaty at the Sacred Mosque? As long as they are upright with you, be upright with them. God loves the pious.
FD wants to tell you that chapter nine is an instruction to all Islam to kill all the Infidel. Firstly the original uses the term Mushrikun not infidel. In the translation I found Mushrikun means polytheists. Greek, Roman, Norse religions follow pantheons of may goods. God's of war. gods of love. Judaeo Christian faiths follow what they call one true good. they are monotheistic. It would appear to me that they are not included in this discussion.
However it would appear that Islam is not alone in dealing harshly with pagan faiths. History tells us .....
The Edict of Milan had been issued by the emperors Constantine and Licinius in 313, and gave official support to the toleration of Christianity. As soon as Christians became influential, the issue of toleration was no longer so important to them. By 330 Constantine was prohibiting pagan rites in Constantinople, his new capital. By around 350 the performance of a pagan sacrifice had become a capital offence*. A few years later, in 391, under Theodosius I, Christianity became the only recognised religion of the Empire. In time the Church, supported by pliant Christian emperors, would eliminate its many rivals, although it would take centuries to achieve a total monopoly. Already, by the middle of the fourth century the Christians were being accused of cruelty exceeding that of wild animals*. All religions except Christianity were suppressed, sacred property was confiscated, holy treasures were seized, temples and shrines were destroyed or taken over as new churches. The ancient rights of sanctuary that had been enjoyed by followers of all religions at their burial grounds were abrogated.
Emperor Karl (Charlemagne) in 782 had 4500 Saxons, unwilling to convert to Christianity, beheaded.
Followers of other religions could be killed with impunity. Dozens of Old Testament passages could be, and were, cited to prove that God approved of mass murder, as in the book of Ezekiel where God orders death for those who have been weeping for Tamuz and those who have been facing and worshipping the sun:
Slay utterly old and young, both maids, and little children, and women
(Ezekiel 9:6)
To my mind none can lay claim to the moral high ground.
